Checking Coolant in the Intercooler System (CTS-V)

Cadillac CTS / Cadillac CTS Owners Manual / Vehicle Care / Vehicle Checks / Engine Coolant / Checking Coolant in the Intercooler System (CTS-V)

The vehicle must be on a level surface when checking the coolant level.

The super charged engine intercooler coolant fill neck is located in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview.

On the coolant fill neck, there is a cold fill region between the two horizontal lines shown.

Check to see if coolant is visible in the coolant fill neck. If the coolant is not visible or below the cold fill region in the fill neck, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant fill bottle, but be sure the cooling system is cool before this is done.
